我的config.yml上有以下配置
ci_api:
file:
purposes:
attachment:
我的配置类看起来像这样:
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('ci_api');
$rootNode
->children()
->arrayNode('file')
->children()
->arrayNode('purposes')
->children()
->end()
->end()
->end()
->end()
->end(); //children
return $treeBuilder;
当我试图运行它时会收到错误消息:
“ci_api.file.purposes”下无法识别的选项“附件”
请注意,根据目的,可能会有无限数量的儿童。
感谢。

只需将原型定义作为数组添加到最后一个元素定义中,如下所示:
$rootNode
->children()
->arrayNode('file')
->children()
->arrayNode('purposes')
->prototype('array') // Add this line
->children()
->end()
->end()
->end()
->end()
->end(); //children
